Transmogrification sets coming in Patch 7.2

Transmogrification is one of the many new features of WOW: Legion. Transmogging allows players to replace gear items appearance that with the look of a different item--Having their appearance customized is always what players pursue in game to be different from others. The legion expansion has already added the appearance tab to make collection more easier, while Patch 7.2 will further help you by adding a new way to track your Transmogrication options with the addition of a Sets tab within the Appearances interface. You can quickly and easily scroll through the available sets for your class, see which items you've collected, and which you have not, for both available PvE and PvP sets. You’ll also be able to see how each set looks on your character without the need to preview each individual piece. (more features please read here)
